Functions

func Checker

func Checker(item interface{}, value interface{}) bool

Checker is a function to be sent to concurrent.Slice.Check to compare transactions. `item` will be the original and `value` will be either the new transaction we're trying to compare or its ID as a `Hash`.

func RebuildTransactionID

func RebuildTransactionID(forTx Transaction) (txID model.Hash, err error)
